Nitrogen Dioxide - an overview | ScienceDirect Topics
2020年5月12日 · Nitrogen Dioxide. Nitrogen dioxide (NO2) is one of a group of highly reactive gases known as nitrogen oxides (NO x). NO 2 is the main source of nitrate aerosols, which form an important fraction of PM 2.5 and, in the presence of ultraviolet light, of ozone. The major sources of anthropogenic emissions of NO 2 are combustion processes.
Nitrogen dioxide: Risk assessment, environmental, and health …
2021年1月1日 · Nitrogen dioxide (NO 2) is a reddish-brown gas with a distinctive pungent, foul smell at higher temperature. It is toxic, a major pollutant, a strong oxidant, and one of the chemical species of oxides of nitrogen (NOx). The atmosphere consists of 78% nitrogen by volume.
Examining the relationship between ambient carbon monoxide, …
2020年12月1日 · The literature concerning the relationship between carbon monoxide (CO), nitrogen dioxide (NO 2), ozone (O 3), particulate matter with a diameter less than 2.5 μm (PM 2.5), and sulfur dioxide (SO 2), and mental health is growing, with epidemiological evidence currently suggesting that relationships may exist for a multitude of disorders and ...
Particulate matter, nitrogen dioxide, and sulfur dioxide and their ...
2023年7月1日 · Ambient air pollution is of worldwide concern, partially attributing to industrialization and urbanization. Of the various air pollutants, particulate matter (PM 10, PM 2.5), nitrogen dioxide (NO 2), and sulfur dioxide (SO 2) are among the most concerning due to their negative impacts on human health and the environment (WHO, 2006).
Nitrogen Dioxide - an overview | ScienceDirect Topics
Nitrogen dioxide is an irritant gas which produces oxidant lung injury similar to that produced by ozone. Nitrogen dioxide is less potent than ozone and few functional or pathological changes have been observed in animals after acute exposures to less than 0.5 ppm nitrogen dioxide. Pathological changes occur primarily in the terminal ...

Long-term exposure to nitrogen dioxide and mortality: A …
2021年7月1日 · Ambient air pollution is among the greatest environmental risks to human health. However, little is known about the health effects of nitrogen dioxide (NO 2), a traffic-related air pollutant. Herein, we aimed to conduct a meta-analysis to investigate the …
Short-term exposure to particulate matter (PM10 and PM2.5), …
2020年9月1日 · This systematic review was conducted to analyse the evidence on the effects of short-term exposure to particulate matter with aerodynamic diameters less or equal than 10 and 2.5 µm (PM 10, PM 2.5), nitrogen dioxide (NO 2), and ozone (O 3), on all-cause mortality, and PM 10 and PM 2.5 on cardiovascular, respiratory, and cerebrovascular mortality.

2014年3月1日 · Nitrogen dioxide (NO 2) is a reddish-brown gas above 21.15 °C; a brown liquid below 21.15 °C; and a colorless solid at about −11 °C.1, 2, 3 It has the following resonance contributors that are responsible for the resonance hybrid structure that is …
Spatiotemporal dynamics of nitrogen dioxide pollution and urban ...
2019年3月1日 · Nitrogen dioxide (NO 2) pollution has drawn great attention, because NO 2 was considered to be the fastest growing air pollutant in the last 20 years as observed by satellites (Richter et al., 2005; Zhang et al., 2012). Thus, the spatial and temporal dynamics of NO 2 pollution have changed considerably over China.
